Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed July '7, 1916. Serial No. 108,061

To all whom it may concern Be itknown that I, JAMns R. HUNTER, a citizen of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented certain new and useful Improvements in Wrenches; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in Wrenches and especially in the provision of a sliding jaw held in different adjusted positions by means of a springpressed ratchet or pawl.

My invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a side elevation of a wrench made in accordance with my invention. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a cross sectional view on line 33 of Fig. 2.

Reference now being had to the details of the drawings by letter, A designates a fixed jaw having a shank B, the end of which is contracted as at B and circumferentially threaded at its end, and O is a handle fitted over said contracted end.

D designates a movable jaw which has a longitudinal slot therethrough to receive the shank portion of the jaw A. A resilient strip, designated by letter E, is fastened to the rear edge of the shank B and bears yieldingly against the wall of the slot and serves to hold the jaw steady when being moved to different positions.

The shank portion of the movable jaw has a recess therein, designated by-letter H, and K is a pawl pivoted to the pinL in a slot in the sleeve J, which fits over the shank portion of the fixed jaw, and the pawl K has its outer edge convexed and provided with teeth N and O is a spring fastened to said handle and bearing yieldingly against the pawl and adapted to throw the same normally at its farthest outer throw. Said teeth of the pawl are adapted to engage over the end wall of the recess in the shank portion of the movable jaw and to hold the latter in different adjusted positions.

Upon reference to Fig. 2 of the drawings, it will be noted that a coiled spring-B is mounted in a recess B formed within the shank portion of the jaw B and one end bears against the inner end of the recess and the other end against the pin 13*, the purpose of which is to normally hold the jaws separated from each other.

In operation, it will be noted that, when the movable jawis moved toward the fixed jaw, the movable jaw will be automatically held in different adjusted positions by the teeth on the concaved edge of the pawl coming in contact with the end of the shank portion of the movable jaw. WVhen it is desired to return the movable jaw to its normal position, it may be done by first depressing the pawl out of the path of the wall of the recess.

What I claim to be new is 1. A wrench comprising a fixed jaw and a sliding jaw with a slot to receive the shank of the fixed jaw, the shank of the sliding jaw having a recess, a spring interposed between the shank portion of the fixed jaw and the wall of the slot, a sleeve upon the shank portion of the fixed jaw, a pawl carried thereby and adapted to engage the end of the shank portion of the movable jaw.

2. A wrench having a fixed jaw with a shank portion having a contracted end, a handle upon the latter, a sleeve upon said shank portion, a movable jaw slotted to receive the shank of the fixed jaw and having a recess in one end, a spring-pressed dog carried by said sleeve and adapted to engage over the end of the recess in the sliding jaw.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
